People Editorial Guidelines Published on June 28, 2024 09:00AM EDT Photo: Brooke Shields/Instagram; Amazon There’s no question that a breezy button-down is essential to the celebrity summer style blueprint. Just ask Brooke Shields, who shared an Instagram photo with her pup aboard a boat last weekend in a perfectly nautical button-down shirt. The actress personalized her look with layered necklaces, a bandana fashioned into a headband, and a pair of thinly framed aviators — and she’s not the only celeb gravitating toward dress shirts for casual outings. Meghan Markle styled an oversized, solid blue button-down with a pair of loose pants and flats while on a walk in Palm Beach, and Oprah wore a black and white striped blouse with cargo pants during a girl’s trip to Japan. A classic button-down is a staple, as it can be worn with linen pants, colorful sneakers, comfy trousers, and more. We found a few budget-friendly options for your summer wardrobe, and prices start at $21.
